941,891. Terminal boards and blocks; plug boards; twopart couplings. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 27, 1962 [April 29, 1961], No. 15583/61. Heading H2E. A terminal arrangement for electrical wiring comprises insulating segments 2, in which conductors are embedded or housed, clamped together in a mounting frame 1 to form a rigid structure. All segments 2, whether moulded around the desired configuration of conductors as in Fig. 3, or shaped to hold contact members as in Fig. 5, are made interlocking for assembly by providing them with projections 5 along one edge and corresponding recesses along the other, and with interengaging studs and surface indentations 8. Two screw-threaded rods 10 pass through aligned holes 9 in each segment and in a central platform integral with the frame 1, and the assembly is finally clamped to the platform 15 by means of nuts 13, 14 and clamping plates 11, 12. The trame 1 is an insulating moulding open at its back and front to give access respectively to wiring terminals 3 and any socket contacts provided. Fig. 4 shows a sockethousing segment having channels 27, 28 and 29 in which resilient socket members 30, 31 and 32 shown in Fig. 5 are loosely accommodated and held by the studs of the next moulding engaging in the channels. Another type of segment (Fig. 2, not shown) contains a metal screening plate.
